fo all lwlkom t may concern:

Be 1t known that I, GEORGE E. HAZARD, a

citizen of the United States, residing at and useful Improvements in Attachmelnts for Automobile Driven Tire Pumps, of.

which the following is a specification, refer- Nence being had therein to `the accompanying drawing.

This invention relates to improvements in attachments for automobile driven tire pumps, and it pertains to that class of pump which comprises an` open-sided gear case, adapted to be connected with an automobile transmission case, whereby the pump is driven bythe automobile transmission gearin Ihe primary object is to provide means whereby a standarized automobile driven tire pump of the above construction can be used in connection with and rdriven by automobiles having' arrangements which would otherwise vprevent the use of the standardized pump.

lhere it .is necessary to make a special pump to meet ,the conditions' of av particu-A lar type Yof gear, 4it adds to the expense of. the equipment and `at the same time should the pump become wrecked or need to bereplaced, it will require the specially constructed pump, thus preventing the use of a standardized ump to thel ineonveniemceV y `the standardized opemng inthe transmlsedy w-ithrflthe transmissionv case and mecha-` nism of Ia car, which otherwise could not use the standardized um Fig. 2 is a detached) end) view of my improvement. l

Fig. 3 is a front elevation of a stand` ardized pump, showing it with my improvement applied thereto. y `Fig. 4 is, a detachedfaceyiew of my improvement. l

Referring now. to the drawings, A represe'nts a standard pump, which comprises a pump housing 1, havingmounted thereon a cylinder, vor cylinders, 2, and a gear case.

3 at one side 'of the housing l. This gear case 3` has an open side 4, which, when used with the standardized car construction, is in communication with the opening 5 of the automobile transmission case 6.

My improvement consists of a separate connecting housing B, which has journaled therein an intermediate or idler lgear 7. This gear is mounted on a shaft 8 that is supported in the housing B, and the` gearq is provided with an elongated hub 9 tohold it against any sliding movement m respect to the shaft 8. The standardized pump A. carries in its' gear case 3 a gear 10, for driving the `pump crank-shaft 11, and this gear 10 is slidable on the end l2 of the shaft 'which'is located in the gearcase 3, .for the purpose ot' movingl the gear 1() in `and out ot' mesh with lthe idler gear 7. This shifting gear 10 is a part of the standardized pump that is used in the standard construction'for automobiles. 1 y y Most ot' the automobiles of the better graded have standardized their transmission case tol receive a driven tire pump of -the type here shown, which has its gear case or' a corresponding standardized size and shape to fit the standardized opening ofthe automobile transmission case. However, there are automobile constructions that have sion case, but have some internal or external,

application to it of the standardized gear case of the pump, and lit is to enable the standardized pump to be connected with the last mentioned construction of automobile that my improvement is devised.

The connecting housing B Vis made of a size to fit the standardized pump gear case 3 and thefstandardized opening 5 in the. automobile case 6. VNThis housing is `hollow, as shown in Fig. 4,' and is )rovided with bolt openings 13, which register with the bolt ,openings in the flange 14, for the bolts l5.' These bolts 15 are elongated and pass through the flange 1 4, and theconnecting housing B and into Vthe automobile transmission case 6, thus clamping the pump construction and the connecting .housing firmly B, forms an intermediate gear mechanismbetween the transn'iission gear 17 and the l pump` gear 10. s f

This improvenrent enables the standardized tiie pump ofthe type described to be voperatively connected with an automobile vthe housing caiiyinga gear to operatively connect gears in the two cases, whereby a ,standardized tire pump construction can bo used with various specialautomobile arrangements whicli otherwise prevents its use.

2.,'l`he combination with an automobile transmission case carrying gears and having a standardized side openin i'communicatin with one ofthe gears, an a standardize tire 4pump construction havinga gear case with a side opening registering with the transmission case opening, .of a separate attachahle connecting housing between and establishing communication between .the openings of thetwo cases, the housing carin fixed mesh with one of the transmission case gears, and the pump gear case having a laterally slidable gear adapted to be move in and out ofniesh with the housin r gear, all combined for the purpose descri d..

. 3. The `combination with an automobile transmission case having transmission gears and a slide opening communicating wit one 1offthe gears, and a standardized tire pump construction having a gear case carrying a pump ope 'ating gear and havlng a side `opening registering with the transmission j ing bolt openings, of a se arate and inderying a gear located in the housing to be i case opening, the two cases having registerpendent housingnhaving bo t openings registering with the bolt openings of the two cases, the housing adapted t-o be placed between the two vcases and establish communication between the cise openings, the housing carrying a gear operatively connecting the pump and the transmission mechanism.

4. Thecombination with standardized tire pump an'd automobile transmission construct1ons,'having registering openings, of a separate connecting housing vadapted to be clamped between the two cases, the housing carrying a gear having its periphery projecting-beyond the inner edge of the housing and into the transmission case, the housing gear operatively connecting pump and transmission mechanisms, the parts combined as and for the purpose described.

In testimony` whereof I hereunto affix my signature.

'GEORGE EDGAR HAZARD.
